ive been a fan of these games for a long while and ive started to speedrun them bc of how the games are
for the first speedrun that had RTA(real time attempt) and the fastest ive gone, its Fifis Fury V2 in 8m 22s

the starting time is at 20s and the run ends when Toonpimp has sex with Fifi, from the Start to the song and sex
ive also speedran Pollys Tale but the fastest run is at 3m 16s and thats TAS'ed but the rng of the game makes it pretty tedious to speedrun

Crackelvania is also pretty nice for a speedrun but its very difficult, the one with the red lizard can be speedran for All Items, but thats about it
